DECKER GUIDE FOR KNITTING MAGIIIITES.

Application filed January e1, 1827, Serial No. 162,547, and in GermanyMay 1%, 1926.

The decl'zers used for narrowing and wideningoperations in knittingmachines are usually carried by slidable rods which, to allow easymovement, must have a small 6 amount of free play. The oscillatory movements set up owing to the free play are magnified in the deckers so thatthe needles of the latter do not reliably cooperate with the knittingneedles with the result that in stitches are often missed and needlesbent.

The object of the present invention is to remedy this defect, and theinvention consists in providing additional decker guides which arespaced from the carrying rods so it that oscillatory movement of thedeckers can be effectively prevented without particular care being takenin the fitting up of the carrying rods.

Fig. i of the accompanying drawings repso resents a cross-section of onearrangement according tothe invention,

6, a front view of Fig. 5.

The deckers 7) are carried by rods a which 30 are arranged to slide insupporting arms 72. lin the arrangement according to Figs. 1 and 2, thedeckers are formed With tail pieces which bear against a stationaryguide rail 6 and slide along the latter.

While the decker tail bears against one side I of the guide rail, abracket d on the tail engages vthe opposite side or" the same so,

in the arrangement according to Figs.

and 6 the brackets d are omitted, and the decker plates are guidedbetween two rigid rails g and I claim:

1. In a straight-bar knitting machine, the combination with deckersmounted on slidable carrier rods, of guide rails arranged so as tosupport the deckers and prevent oscillatory movements.

2.111 a knitting machine with decker plates, a guide rail arranged so asto support the decker plates, and brackets secured to said plates so asto engage the reversed side of the guide rail.

8. In a knitting machine with decker plates, rails arranged above andbelow said vent oscillatory movements.
